CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 229,849, dated July 13, 1880.

' Applicationfiled June 5,1880. (No model.)

To all whom it may concern:

ing to be a full, clear, concise, and exact description thereof, reference being bad to the accompanying drawings, making a part of this specification,in which-like letters indicating like parts- ,Fignre 1 is alongitudinal sectional view of a coupling. embracing my improvement, and Fig. 2 is a perspective view thereof.

My present invention relates to a coupling a and draw-head having the general features of the'ordinary construction, but with certain improvements added, which better adapt it for the purposes for which it-is intended.

As shown in the drawings, it consists of two uprights,"a, which, with the rear perforated end, I), are forged in the usual way from an upright of suitable proportion and then bent with scarf ends, as represented by the lines 0, to the shape substantially as shown, a hole, I), being punched in the rear end by which to make connection with the car-body.

The draw-head proper is forged between suitable dies in any of the ways known to the art, but for convenience in two pieces, the line or plane of division being represented by the line 0.

In forging draw-heads of this description it has heretofore been usual to extend the uprights a of a uniform width up to their junction with flange-head, or bull-nose, as it is sometimes called. Pin holes d being then punched, the vertical plane which passes transversely through the, draw head and through the holes 61 indicates the plane of the least strength, and, in fact, the usual breakingpoint of such'devices.

To obviate this objection and secure the necessary strength at that point, I curve out the heavy fillets a at the angle formed by the uprights a with the bullnose, and extend them out until they meet the flanges f of the bull-nose,whereby I secure the desired strength at that point.

It has also been found that where the upper which usually is provided, as shown, at l, and

which when in use draws by the post l.

To overcome these objections in making the lower part of the bull-nose, I forge up what may be termed a bridge, l&, which I make preferably of the height equal to the thickness of the link 1, though it may be made higher if so preferred. The lower end of the pin will pass through or back of this bridge, so that the length of pin subject to strain in the drawing of cars is lessened by an amount equal to the height of the bridge, and consequently the danger of breaking the pin is correspondingly lessened. Also, the bridge aids in holding the link in the position more nearly horizontal for purposes of coupling, and also, by its sloping forward face 12/, aids in coupling, and still fun ther protects the permanent link I, which is lying back of it. These parts of the coupling are forged or shaped in separate pieces by means of suitable dies, or in any of the ways known to the art, and are united by welding along the scarf-line c c and e, and the device being otherwise finished in the usual wayit is ready for sale or use.

I claim herein as my invention- A forged draw-bar and coupler containing fillets to, extending from back of the pin-holes d to the periphery of the flange of the bullnose, and a bridge, a, resting above the upper level of the lower upright in the path of the pinhole, substantially as set forth.

In testimony whereof I have hereunto set my hand.

JOHN '1. WILSON.
